What is the difference between welds G30 and G33 for the connection of the nozzle to the cylinder in HG/T20583? How to choose if both conditions are met simultaneously? I seek answers from experienced engineers
Selected based on the welding conditions of the equipment, G30 is generally used in situations where there is sufficient space inside the equipment, making welding easier and more convenient. G33 is used when the welding conditions inside are not as favorable, in order to minimize the amount of work required for welding inside.
Is it the 2020 version? The welds on the G30 reinforcement ring are small, while those on the G33 reinforcement ring are larger than the welds on the cylinder body ； G30 is probably the weld on the head. The cylinder welds are all welded inside the equipment.
